Vocational aptitude tests are used to test an individual's capacity to be trained for various occupations by testing various types of aptitude. Generally, they include batteries or groups of tests each designed to test a specific aptitude. After a test is scored, test administrators use accepted standards to determine which occupations are best-suited for an individual's various aptitudes.

Personal Experience Influences Scores — Vocational aptitude tests are biased by the personal experience of the test taker. People with disabilities who not exposed to experiences that develop special skills and may not test as well in these test areas even if they are interested or inclined to pursue related jobs (e.g., they were not encouraged to tinker with home appliances or take a shop class in high school).

Career Counseling Based on Biased Test Scores – Career counselors and vocational evaluators often use these tests to provide career guidance. However, tests that contain biased language and questions often incorrectly assess a person's aptitude. For example, if a woman does not demonstrate mathematical and spatial abilities on a test because it contains gender bias, a counselor may not encourage her to enter jobs requiring those abilities, such as trade and technical occupations. This type of problem can also occur with other types of bias related to people with disabilities.
